I'm working on a bootstrap of gcc-4.6.1 using Sun Studio on Solaris 9.
I'm currently stuck at a liblto_plugin.so linking issue[1], but I'd
first like to verify whether my general approach is correct.
libtool doesn't seem to have noticed you are not using gcc/linux.
There is a mutual incompatibility between flags accepted by Sun Studio
and GCC. Therefore, 2 sets of CFLAGS are needed: one for the host
compiler (here: Sun Studio), and one gcc for the subsequent stages.
The first one is set via CFLAGS, and the second one is set via
CFLAGS_FOR_TARGET. Is this approach correct? (I also saw references
to the TARGET_CFLAGS variable, so I'm not sure which one to use.)

(BOOT_CFLAGS)
But you should probably leave alone the flags used by gcc and only touch
the flags used by suncc (although the default ones worked well enough last
I tried).
